JAMES C. ANDERSON, OF HIGHLAND PARK, ILLINOIS.

WHEEL FORAUTOTRUCKS.

SPECIFICATION forming part of Letters Patent No. 642,777, dated February6, 1900.

Application filed August 25, 1899. Serial No. 728,443. (No model.)

To all whom it may concern:

Be it known that 1, JAMES C. ANDERSON, a citizen of the United States,residing at Highland Park, in the county of Lake and State of Illinois,have invented certain new and useful Improvements in WVheels forAutotrucks, 850. and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to certain new and useful improvements inwheels'designed for carrying heavy loads, and especially adapted to theuse of a novel tire forming the subjectmatter of another applicationfiled by me August 11, 1899, Serial No. 726,887, and has for its objectthe production of a wheel composed entirely of metal and adapted to haveone-half of the rim-flange readily removed and replaced in order that anew collapsible pneumatic tire may be put in position and rigidlysecured in place.

With these ends in view my invention consists in the details ofconstruction and arrangement hereinafte rdescribed, reference being hadto the accompanying drawings, in

' which- Figure 1 is a side elevation of a segment of a wheel embodyingmy improvements and provided with a tire made in accordance with theinvention described in the pending application hereinbefore referred to,and Fig. 2 is a cross-section on the line y 'y of Fig. 1.

Similar letters of reference indicate like parts in both figures of thedrawings.

E E are two disks of sheet-steel struck up into the form at Fig. 2, withan opening in the center to receive the hub F, composed of a section ofsteel tubing. The disks E and E flare outwardly toward the center andsurround the hub F. They are each formed with an annular flange G,within which the l1ub is firmly secured byradial rivets H. The

disks contact for about one-third of their radius and are rigidlyconnected by rivets I at suitable distances apart. The disk E terminatesin a curve constituting one half J of the tire-rim. The other half J ofthe rim is made separate and is secured to the disk E by removablescrew-bolts K and nuts K. The interiorperiphery of rim J rests upon theperiphwhen the said rim is secured in place the disk E and its rim aresubstantially the same as the disk E and its rim. Each of the rimportions is provided with a series of perforations M, and when the tireAis secured in position within the rim the resilient body of the tirewill, under the expansive force of the contained air, be forcednipple-like into the perforations M, as clearly shown at Fig. 2. Thesenipple-like projections constitute checks or detents against thecreeping action of the tire within its rim.

The hub F is provided at each end with a ball-cup O, which is secured inplace in any well-known manner. I

P is the axle, threaded at each end to receive cone-nuts Q, betweenwhich and the ball-cups O are confined antifriction-balls R. Dust-platesS close the open ball-cups by contacting with the outer ends of thecone-nuts Q and are held in place by jam-nuts T, between which and nutsUare confined the forks or other frame-supports V.

\Vhen it is desired to remove the tire N, the nuts K are removed andbolts K withdrawn, whereupon the rim J may be taken away, leaving thetire free for removal in an obvious manner.

WVhile I have shown the disks imperforate on their faces, it will beunderstood that when metal of sufficient gage is used to permit it thefaces of the disks may be perforated in any fanciful form to lighten thestructure without destroying its strength.

The construction and arrangement of the hub and axle and the connectionwith the disks E and E may be varied without departin g from the spiritof my invention, although I prefer the construction shown as one veryeconomic and efficient.

The important feature of my invention in my improved Wheel resides inthe sheet-metal disks and rim J J, so constructed that a nondeflatabletire may be put in position and readily removed, as hereinbeforeexplained.

I am aware that wheels have been made of two dish-shaped disks of sheetmetal secured by rivets to a hub, and that the peripheries of the saiddisks have been extended laterally to constitute, when the disks areriveted together, a rigid and continuous rim for the reception of atire, but such rims are only adapted to receive a collapsible ordeflatable tire, and I do not wish to be understood as claiming any suchconstruction; but

What I do claim as new, and desire to secure by Letters Patent, is-

1. A wheel adapted to carry a non-deflatable pneumatic tire andconsisting of two sheet-metal disks E and E, secured together andsurrounding and secured to a central hub, one of said disks Eterminating peripherally in one half J of a tire-rim, and the other diskE, of less diameter and minus a rim portion, in combination with a rimportion J corresponding with the rim portion J of the disk E and formedwith a radial Web secured in position by screw-bolts and nuts K and Ksubstantially as and for the purposes set forth.

2. In a wheel adapted for use with a nondeflatable tire, metal disks Eand E constructed and secured together as described, and formed withhub-flanges G, G, in combination with a tubular hub F, radial rivetsI-I, ball-cups O, axle P, cone-nuts Q, dust-plates S, balls R and nuts Tand U, substantially as and for the purposes set forth.

vIn testimony whereof I affix my signature in presence of two witnesses.
